Underwater telecom cables make superb seismic network

(University of California – Berkeley) Photonic systems can transform underwater fiber-optic cables into a dense network of seismic stations to illuminate ocean-floor earthquake zones impossible to study today, according to a new study by researchers from UC Berkeley, Berkeley Lab and Rice University. The scientists turned 20 kilometers of cable around the underwater San Gregorio Fault system in Monterey Bay into an array of some 10,000 seismic sensors by interferometrically measuring backscattered light caused by strain along the cable.

Princeton scientists discover surprising quantum effect in an exotic superconductor

(Princeton University) Superconductors are already in use in various capacities, but newer iron-based superconductors have potential for future use. Researchers led by a Princeton team have studied what happens to the superconducting nature of these materials when impurities are added. The results shed light on how superconductivity behaves in these materials.

Individual climate models may not provide the complete picture

(Penn State) Equilibrium climate sensitivity — how sensitive the Earth’s climate is to changes in atmospheric carbon dioxide — may be underestimated in individual climate models, according to a team of climate scientists.

Photosynthesis seen in a new light by rapid X-ray pulses

(Arizona State University) In a new study, led by Petra Fromme and Nadia Zatsepin at the Biodesign Center for Applied Structural Discovery, the School of Molecular Sciences and the Department of Physics at ASU, researchers investigated the structure of Photosystem I (PSI) with ultrashort X-ray pulses at the European X-ray Free Electron Laser (EuXFEL), located in Hamburg, Germany.

UK needs to act to prevent electric vehicle battery waste mountain — new study

(University of Birmingham) Recycling technologies for end-of-life lithium ion batteries (LIBs) are not keeping pace with the rapid rise of electric vehicles, storing up a potentially huge waste management problem for the future, according to a new study.

Breaking down controls to better control wind energy systems

(Chinese Association of Automation) Researchers based in Brazil have developed a way to better control wind energy systems in electrical generation. Wind energy systems are typically expensive to maintain, and they can only convert a portion of their produced energy into storage. The results were published on IEEE/CAA Journal of Automatica Sinica, a joint publication of IEEE and the Chinese Association of Automation, and could have implications for making wind energy systems more efficient and cost-effective.

Should I unplug my appliances and, if so, will I save money on my electric bill?

All things plugged in will bleed some energy. Called “standby” electricity loss because it’s so often associated with electronics in standby or idle mode, it’s also known as “phantom” or “vampire” electricity (for obvious reasons). Even turned off, many appliances…

Rice yields plummet and arsenic rises in future climate-soil scenarios

(Stanford’s School of Earth, Energy & Environmental Sciences ) Research combining future climate conditions and arsenic-induced soil stresses predicts rice yields could decline about 40 percent by 2100, a loss that would impact about 2 billion people dependent on the global crop.
